Glioblastoma (GBM) is one of the most lethal brain cancers worldwide, and there is an urgent need for development of novel therapeutic approaches. Parecoxib is a well-known cyclooxygenase-2 (COX-2) inhibitor, had already been developed for postoperative analgesia with high efficience and low adverse reaction. Recent study suggested that parecoxib potently enhances immunotherapeutic efficacy of GBM, but its effects on GBM growth, migration and invasion had never been studied before. In the present study, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and, BrdU (5-Bromo-2-deoxyUridine) incorporation assays were used to evaluate the cell proliferation of GBM cells...

Transarterial chemoembolization(TACE) is the palliative treatment of choice for patients with unresectable hepatocellular carcinoma (HCC). The 242 patients prospectively enrolled in this study were diagnosed with HCC and received TACE at Sun Yat-Sen University Cancer Center between October 2014 and March 2015. Patients were divided into study and control groups based on whether parecoxib sodium was administered postoperatively. Postoperative pain, body temperature, vomiting, changes in liver function, physical activity level, length of hospital stay, and tumor control were evaluated...

Surgical stress and inflammatory response induce the release of catecholamines and PGs, which may be key factors in facilitating cancer recurrence through immunosuppression. Animal studies have suggested the efficacy of perioperative blockades of catecholamines and PGs in reducing immunosuppression. In this study, to our knowledge, we present the first report of the effects of perioperative propranolol and/or parecoxib on peripheral regulatory T cells (Tregs) in breast cancer patients. Patients were randomly assigned to control, propranolol, parecoxib, and propranolol plus parecoxib groups...

OBJECTIVES: Pain is one of the most common side effects of transcatheter arterial chemoembolization (TACE) treatment. This study aimed to assess the analgesic effect of parecoxib sodium for postoperative pain control in patients with inoperable hepatocellular carcinoma (HCC) undergoing TACE. MATERIALS AND METHODS: This randomized placebo-controlled prospective clinical study was conducted at a single cancer centre. Patients were randomly assigned to receive parecoxib sodium (experimental group; n = 60) or 0...

OBJECTIVE: To discuss the effect of preemptive analgesia with parecoxib sodium in patients undergoing radical resection of lung cancer. METHODS: 115 cases of lung cancer patients with American society of anesthesiologists class (ASA) grade I~II who received selective operation were randomly divided into the research group and the control group. The research group patients were given preoperative parecoxib sodium 40 mg plus postoperative normal saline 2 ml, while the control group patients were treated with preoperative normal saline 2 ml plus postoperative parecoxib sodium 40 mg...

BACKGROUND: To study the effect of parecoxib, a novel cyclooxygenase-2 selective inhibitor, on the radiation response of colorectal cancer (CRC) cells and its underlying mechanisms. MATERIALS AND METHODS: Both in vitro colony formation and apoptosis assays as well as in vivo mouse xenograft experiments were used to explore the radiosensitizing effects of parecoxib in human HCT116 and HT29 CRC cells. RESULTS: Parecoxib sensitized CRC cells to radiation in vitro with a sensitivity enhancement ratio of 1...

Analgesic treatment with anti‑inflammatory drugs may aid the prevention of postoperative pain and the attenuation of the postoperative immune inflammatory response. The current study presents a randomized, double‑blind controlled study, which was performed to investigate the levels of Th1, Th2, Th17 and Treg cytokines, including interleukin (IL)‑2, interferon (IFN)‑γ, IL‑4, IL‑10, IL‑17, IL‑23 and transforming growth factor (TGF)‑β in the peripheral blood of patients with cervical cancer following laparoscopy...

This study was designed to compare the analgesic effects of cryoanalgesia and parecoxib in lung cancer patients after lobectomy. A total of 178 lung cancer patients awaiting large-sized lobectomy were enrolled in the study. The patients were randomly divided into Group A (intercostal nerve cryoanalgesia) and Group B (parecoxib). The analgesic and adverse effects were compared between the two groups. The pain score of Group A was significantly lower than that of Group B (P < 0.05). The patients in Group A used significantly less morphine than those in Group B (P < 0...

Cyclooxygenase (COX) inhibition has been shown to prevent the development of esophageal adenocarcinoma (EAC). However, the potential of this approach for treatment of established cancer has been poorly investigated. Our objective was to determine whether non-selective or selective inhibition of the COX pathway affects the growth of esophageal adenocarcinoma xenografts in nude mice. A human esophageal adenocarcinoma xenograft model was established by subcutaneous inoculation of OE33 cells in nude mice. Small tumor slices harvested from four OE33 xenografts were implanted in the flanks of new mice that were randomized to different treatments (6 animals per group): indomethacin (3 mg/kg/day), parecoxib (0...

BACKGROUND: Preincisional pain management aims at reducing pain and inflammatory response. We investigated whether preincisional parecoxib administration reduces pain, opioid requirements, and cytokine production after surgery for colonic cancer. METHODS: Forty one patients whose American Society of Anesthesiologists (ASA) status was I-II and who were scheduled for colorectal cancer surgery were randomly divided in two groups according to the timing of parecoxib administration: Group PRE (preincisional) received parecoxib 40 mg intravenously 30 min before skin incision and group POST (postincisional) received the same dose 30 min after skin incision...

BACKGROUND & AIMS: Cyclooxygenase-2 inhibitors reduce colon cancer risk by mechanisms that are not fully understood. We performed microarray analysis of adenomas from Apc(Delta14/+) mice to identify genes that respond to these drugs. METHODS: Apc(Delta14/+) mice were given a single daily injection of parecoxib for up to 9 weeks; intestinal tracts of these and control mice were analyzed by microarray analysis, immunohistochemistry, in situ hybridization, and quantitative real-time polymerase chain reaction...

PURPOSE OF REVIEW: This review addresses recent concerns about the cardiovascular safety of nonsteroidal anti-inflammatory drugs, the disease-modifying role of these drugs in ankylosing spondylitis, and their use in the understudied pediatric population. RECENT FINDINGS: Several recent observational and controlled studies highlight the cardiovascular toxicity of rofecoxib, celecoxib, parecoxib, valdecoxib and naproxen. Concerns about cardiovascular safety raise questions about the chronic use of nonsteroidal anti-inflammatory drugs in patients with rheumatic diseases, including children...

BACKGROUND: Inhibition of the COX-2 enzyme has been shown to have a radiosensitizing effect in epithelial cancers. The aim of this study was to investigate whether the efficacy of radioimmunotherapy (RIT) using 131I-labeled anti-CEA monoclonal antibody MN-14 could be enhanced by co-administration of the selective COX-2 inhibitor Parecoxib in mice with small volume (1-3 mm) peritoneal carcinomatosis of colonic origin. METHODS: First, the efficacy of 14 daily injections of Parecoxib monotherapy (0-0...
